BED-SPRING.

To all whom it may concern:

Be 1t known that I, MONTGOMERY SLEETH,

-a citizen of the United States, and a resident ofthe borough of Bellevue, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Bed-Springs; and I do hereby declare the following to be a full, clear, and exact. description thereof.

, Iy invention relates to bed-springs and has special reference to such springs preterably. for use on bed-steeds of a size-larger or wider than single beds, such'as doublebeds, three-quarter beds, etc.

The object of my invention is to provide such a bed-springthat will enable one side of the same when in use to maintain a substantially level or horizontal position on its top, or when both sides of the bed are in use and by persons of different weights, and a still further object of the invention is to provide such a bed-spring in which the top of the same will be made flexible when in use.

To these ends my invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved bed-spring, I will dereferring to the accompanying drawing, in which Figure-1 is a plan view of my improved bed-spring showing the folding type in an open position and with the springs removed from one side. Fig. 2 is a side elevation of the same in its closed position. Fig. 3 is a View of one of the rods for connecting the upper ends of the springs together. Fig, 4 is a view of one of the spring rods for connecting the upper ends of the springs. Fig. 5 is an enlarged plan view showing the connectin of the upper ends of the springs. Fig. I is an end view. of a portion .of the: Fig. 7 is -51. perspective view of a portion of -a spring having a single rigid lower f ramc.

Like symbols of reference herein indicate like parts in each of the figures of the drawmg.

As illustrated n the drawing my invention is shown as applied to a folding bed-' I Specification of Letters Patent. Application filed May 8, i913. Serial No. 768,344.

spring a, which is com osed ofithe two'sections A and B, each 0 which has a rectangular frame 1 for forming the bottom of the spring, and such sections are connected together at their top portions so as to fold on each other, as hereinafter described. Above each of the lower frames 1 is the rectangular frame 2, which is split or divided longitudinally of the spring and on each frame 1 i as at 3,-to form the two side frameportions 2 of rectangular shape, and these portions 2 above each of the frames 1 are connected together so as to extend across the spring by the hin es 4.

The rarnes l and 2 are connected together by a plurality of sin le volute helical springs 5, the lower or smaller ends of such springs being's'ecu'red to the side and end portions 1 of the lower frames 1 and to bars or slats 6 within and extending across said framesl,

ivhile the opposite or larger ends of suchlsprings are supported within the upper .frames 2 by the outer springs being connccted in any suitable manner to the side and end portions 2 ofthe said frames and the intermediate springs being connected toeach other and to said outer springs, as hereinafter described.

Extending diagonally betweenthe upper.

ends of theouter and inter oediatesprings 5 and between the upper ads of such intermediate springs are the spring rods or bars 6, each of which is in the form of a straight helical spring, and is connected to the springs 5 by its ends being bent around said spring ends, while extending between the upper ends of the outer and intermediate springs 5 v and between v such ends oi said intermediate springs are the bars or rods 7, each of which passes through each of said spring bars 6 and is (miner-ted by its ends being bent around said spring ends. These spring bars (3 and rods 7 are o connected to their respec- 'tive springs as to allow the crossing of the bars 6 and rods 7 in their connection with "four of such springs, which will thus place the said bars 6 and the said bars 7 in a diagonal position respectively to four of the said springs 5 and in a'diagonal position alternately across the bed spring a, thereby allow'ng the springs 5 to remain in line with em other lengthwise and crosswise ofthe: s ring.

it. will thus be seen that my improved bed- Q ijo'i'sss spring will enable the topbf the same, when used, to b e flexible at all times by reason of the connections between the,spr'1ngs of the same, 'and such bed-spring will also enable the spring or res lient connection between.

the tgp of the springs to be made in a cheap and rapid manner, without much labor or expense and without the useof complicated while parts or clamping connections. It will also be seen that-a person 1151115 one side of the.

bed-sprin onpersons of, fi'crent weights using sides of the same eachside .of such s ring will maintain a substantially fiat or 'orizontal position at all times, which .4 wiilthereby prevent the uncomfortable feel- 1ng to such person or persons when the top of the s )rin r is irr ular or on the usual inis n cline when in such use, as in ordinary con structions.

If desired, my invention can be applied to abed-spring other than the folding or hinged type and different forms of springs and materials can be used in the bed-spring,

various other modifications changes in the design, application and con- 'struction of my improved bed-spring may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages,

1. A bed spring comprising a single rigid and v -What I claim as my invention and desire to secure by Letters Patent 1s:

lower frame and a plurality of separate upper frames, springs between said upper and lower frames, said upper frames extending longitudinally to form a plurality of separately operative spring sections.

A 2. A bed spring comprising a lower and an upper frame having a spring portion therein, said lower frame being divided crosswise at its center, and said upper frame being divided'crosswise and hinged and dividech-iengitudinally to form. a plurality of separately operative-spring sections.

3. A 'springstructure consisting of a frame, springs supported by said frame, a spring bar-diagonally connecting the upper coils of two springs, and a rod diagonally connectin the upper coils of two other springs'a joining said first two springs, said rod crossing said spring bar.

4.'A spring-structure consisting of a frame, springs supported by said frame, a

helical spring bar dia onally connecting the
